# Check Home Assistant State #

A check plugin for [Nagios](https://www.nagios.org/)/[Icinga](https://icinga.com/)/etc. that queries [Home Assistant](https://www.home-assistant.io/) for the current state of entities.

## Requirements ##

- [Python](https://www.python.org/) >= 3.8
- [requests](https://pypi.org/project/requests)
- [nagiosplugin](https://pypi.org/project/nagiosplugin/)

## Usage ##

You will need a token for Home Assistant's REST API.
[Instructions to aquire one can be found here](https://developers.home-assistant.io/docs/api/rest/).

At a minimum, you need to specify the token, home assistant url, a device class to filter by, and warning/critical ranges.
Example:
```sh
./check_home_assistant_state.py --token $HASS_TOKEN --url $HASS_URL --device-class battery --warning 20:100 --critical 10:100
```
See `--help` for more features/arguments.

A CheckCommand config for Icinga2 can be generated with `--make-icinga-conf`.
